COAL-FILING APPARATUS.

Specification of Letters Patent.

Patented April 30, 1907.

tain Improvements in Coal-Piling Apparatus,

of which the following is a specification.

My invention relates to certain improvements in conveying apparatus ofthe type used in storing materials in piles.

My invention is particularly adapted to a type of conveyer in which ametallic ribbon is used as the bottom of the carrying portion of theconveying apparatus, the ribbon being longitudinally adjustable to shiftthe point of discharge, as set forth and claimed in the patent grantedto James M. Dodge on Feb. 17th, 1891,.No.i l6,l36.

The object of my invention is to dispense with the usual drum forcarrying that portion of the ribbon not in use and to provide means bywhich the ribbon can be more easily handled.

Referring to the accompanying drawings: Figure 1, is a side view of anelevating conveyer, known as a trimmer, illustrating my invention; Fig.2, is an enlarged sectional view on the line 2*? Fig. 1; Fig. 3,isaperspective view of the ribbon and its operating cable, and Figs. A and5 are enlarged views of portions of Fig. 2.

B is a truss structure adapted to travel on rails a-a. This trussstructure is mounted on a truck I) at the lower end and its upper end issupported by a frame I) carrying traction wheels. The rail a issupported at intervals by standards A made in any desirable i orm. Thewheels at the lower end of the truss structure, as well as at the upperend, in the present instance, are driven by suitable mechanism so thatthe truss structure may be traversed across the piling floor.

The truss structure carries a conveyor 1), in the present instance,consisting of a chain (1 having a series of 'llights d. This conveyorpasses around a foot wheel (1 at the lower end of the truss structureand around a head wheel (Z at the upper end or' the truss structure andit is driven in the direction indicated by the arrow, Fig. 1, by anysuitable mechanism. The lower run is the convey ing run and the upperrun is the return run of the conveyer. The conveyer is supported by theusual means on both runs and the material is carried from the receivingpoint at the base of the structure to the point of discharge over aribbon or metallic band E. This ribbon is made of sheet metal and hasbeen usually wound upon a drum at the base of the truss structure asshown in the above mentioned patent and is adjustably mounted in guides.

By my invention I dispense with the drum at the base of the trussstructure and provide guides ee at each side to support that portion ofthe ribbon which forms the bottom of the trough, plates f-fiorm thesides of the trough as illustrated in Fig. 4. There are guides e on theupper portion of the truss structure, as illustrated in Figs. 1 and 2,for that portion of the apron not in use. The apron, in the presentinstance, passes over a series of rollers c at the base of thestructure, as clearly shown in Fig. 3, but a wheel may be used ifdesired.

F is a cable attached to the forward end a of the apron and this cablepasses around a sheave f at the upper end of the truss structure andthen by preference around another sheavef to a driven drum or drums tothe rear end 6" of the apron to which it is attached so that the apron Eand the cable F form, in fact, an endless structure.

It will be understood that the driving mechanism of the structure may bea single drum, upon which the cable F may be wound one or more times, orit may be formed of two cables both attached to a drum, or toindependent drums, as desired; the main. feature of the invention beingto so construct the apparatus that that portion 01" the ribbon not inuse is carried in a comparatively flat condition by guides on the trussportion of the structure. By this means I dispense with the drum uponwhich the ribbon is usually coiled at the base of the structure and Ialso dispense with the operating mechanism at the base of the structure.

The operation in the present instance is as lollows:The coal is firstdischarged at a point near the piling lloor forming an initial pile andwhen the apex of the pile reaches the discharge point c of the ribbonthen the ribbon is moved longitudinally, shifting the discharge point sothat coal will be discharged at a higher elevation and at a point beyondthe apex previously formed, and this horizontally as in some types ofconveyers.

I claim I 1. The combination in a conveying apparatus, of a frame, anendless belt conveyer carried by said frame, a movable ribbon formingthe bottom of the trough of the said conveyer over which the conveyertravels, guides for that portion of the ribbon not in use, and a cableconnected to both ends of the ribbon, with means for engaging the cablefor longitudinally shifting the ribbon, substantially as described.

2. The combination of a truss structure arranged at an inclination, anendless belt conveyer mounted on said truss structure, wheels at eachend of the structure around which the conveyer passes, guides on thestructure below the lower run of the conveyer, and guides on thestructure above the upper run of the conveyer, a ribbon arranged totravel in said guides, a cable connected to each end of the said ribbon,and means engaging the cable for moving the ribbon longitudinally in itsguides, substantially as described.

8. The combination of an elevating conveyer, a truss structure arrangedat an inclination, an endless flight conveyer mounted on the saidstructure, wheels at each end of the structure around which the saidconveyer passes, means for driving the conveyer, a trough mounted on theunder side of the conveyer, said trough having an open center and guidesat each side of the trough, guides on the structure above the return runof the conveyer, and guides at the lower end of the structure, with aflexible ribbon adapted to the said guides, a cable attached to each endof the apron, sheaves at the upper end of the structure around which thecable passes, and means engaging the cable for longitudinally moving theribbon, substantially as described.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing Witnesses. i

I CHARLES PIEZ.
